Synthesis and optical properties of novel apatite-type NaCa3Bi(PO4)3F:Dy3+ yellow-emitting fluorophosphate phosphors for white LEDs

Multifunctional dielectric/optical response with broadband white light emission in a hybrid stannic halide crystal

“…39,40 Subsequently, many dielectric multifunctional materials emitting various colors, such as red, green, yellow, blue, and others, were explored, significantly enriching the development of fluorescent dielectric multifunctional materials. 38,[41][42][43][44][45] Luo et al also reported white light dielectric responsive lead-based materials, which have a warm white light a color temperature of 4423 K and have high color rendering index (CRI) of up to 86. 28 Despite these great advances, the single material simultaneously equipped with a dual channel optical/electrical response of dielectric switching response and intrinsic broadband white-light emission has been very rare and an ongoing challenge.…”

Tb3+ and Sm3+ co-doped Ca2La3(SiO4)3F phosphor: synthesis, color regulation, and luminescence properties

“…Samarium has the potential to generate red light when used as a phosphor activator, whereas terbium has the potential to emit green light when used as a phosphor sensitizer. [11][12][13] An apatite compound is oen selected to serve as the host because of its changeable crystal eld environment and its strong chemical stability, which is unaffected by the former. M 10 (XO 4 ) 6 Y 2 is the chemical formula for the apatite structural compound and M might serve as a monovalent cationusually an alkali metalbut also a trivalent cation like a lanthanide element, or even a divalent cation like an alkaline earth metal; X denotes S, Ge, Si, and P, among others; Y is most commonly shorthand for the element halogen and the element oxygen, both of which function as channel anions.…”
